Areas vs. industries vs. categories. Industries describe who buys an API (financial services, healthcare). Categories describe what an API does (analytics, payments, identity-access). Areas organize the reference material behind a subject — the specs, tools, and docs of schema design, data modeling, or cybersecurity standards — the topical knowledge base that powers the API Evangelist areas.
